Most of the things that look like a broken coffee maker aren't one. Before you start thinking about a replacement, it's worth five minutes with this list — the majority of what reaches Wilfa support turns out to be limescale, an empty tank, or a switch nobody knew was there.
If your Wilfa coffee maker won't start, check three things in order: that it's plugged in, that the power switch on the machine itself is set to I, and that there's water in the tank. If it starts but no water comes through, the cause is almost always limescale and the fix is a descale. Everything else is below.
There's a power switch on the machine that's easy to miss — it isn't the brew button. On the Performance models it sits at the back; on others it's underneath the base, on the left, beneath the water tank. It needs to be set to I.
Work through it in this order: check the plug and socket, find that switch and set it to I, then check there's water in the tank. If all three are right and the machine is still completely dead, it's a warranty conversation rather than a home fix.
A steady blink with no brewing almost always means the water tank is empty, or isn't seated properly. Refill it, push it home until it sits flush, and try again.
On some models the machine also needs a refill before it will restart after switching itself off — that's normal behaviour, not a fault.
This is the single most common fault Wilfa is asked about, and it's limescale. Scale narrows the flow path inside the machine until the pump can no longer push water through it.
The fix is a proper descale with Brewfresh Universal Descaler, followed by a full tank of clean water to flush the system, then a retest. If the machine has been neglected for a long time, one descale may not be enough — run a second one before you conclude it's beyond help.
Our step-by-step descaling guide covers the whole process, including the vinegar method if you don't have descaler in the house.
The machine has decided there's no water in the tank, even though you've just filled it.
There's a small white plastic float in the bottom of the water tank that tells the machine the water level. It can stick — and neglected descaling is almost always the reason. Tap it gently free with the handle of a teaspoon or a thin screwdriver. If you can't reach it, remove the carafe, the water arm and the filter holder and turn the machine upside down over the sink.
Once it's moving again, descale the machine. A stuck float is a symptom, not the illness.
Coffee coming over the rim of the filter holder has four possible causes, and it's worth checking them in this order:
To clear an overflowing holder right now: set the flow control to the largest setting — 1.25 — and rinse it under running water.
This one isn't a fault at all, and it surprises a lot of people moving to Wilfa from a conventional drip machine.
Most filter machines use a flow-through heater and sit almost silent. Wilfa's Performance and Zense machines use a pump instead, which is what allows them to hold water between 92 and 96°C from the first drop to the last. The pump also empties the system after every brew, so there's no stale water sitting inside between uses. That emptying cycle is the loudest part, which is why the noise is most noticeable right at the start and right at the end.
It's the sound of the thing that makes the coffee good. If you want the detail on why the brew temperature matters, we've explained what ECBC approval actually certifies.
If you're using a thermal carafe, the carafe is almost certainly the problem rather than the machine. A cold stainless steel carafe will pull a surprising amount of heat out of the coffee in the first minute.
Rinse it out with hot water first, empty it, then brew straight away. It makes a bigger difference than people expect.
If you're on a glass carafe and a warming plate, remember the plate switches off after 40 minutes by design — that's an EU requirement, not a fault. Restarting the machine to get the plate going again is possible but not recommended, because running the pump without water wears it out.
It almost certainly isn't. After washing, water gets trapped in the groove between the carafe's outer and inner sections, then runs down the outside when you pour — which looks exactly like a leak.
Dry the carafe thoroughly, including that seam, and the problem disappears.
While we're on carafes: the lid catches people out too. Line the arrow up with Unlock to fit the lid, then turn it to Lock to seal. To pour, turn from Lock to the spout symbol. If the lid won't come off, wiggle it gently side to side to break the vacuum rather than pulling harder.
This is the one fault on the list you can't fix at home, and it's worth recognising so you don't waste a weekend on it.
A rapid, continuous blink signals an internal fault. There's no authorised repair route for it. Contact the retailer you bought the machine from, with your receipt, and make a warranty claim. Every Wilfa product bought after 1 September 2020 carries a five-year warranty, and you don't need to have registered anything — the receipt is the warranty certificate.
A cracked carafe, a lost lid or a scratched water tank doesn't mean a new coffee maker. Wilfa sells replacements for most of what breaks or goes missing, from an £11.20 jug lid upwards:
| Part | Fits | Price |
|---|---|---|
| Replacement server | Performance Compact | £35 |
| Water tank | Performance Compact | £25 |
| Thermo jug, 1.25L | Performance Thermo | £75 |
| Jug with lid | Zense | £35 |
| Filter basket | Svart Performance | £30 |
| Replacement server | Classic+ | £35 |
The full range is in accessories and spare parts, and we've written about why replacing the part beats replacing the machine.
Why won't my Wilfa coffee maker turn on?
Check three things in order. First the plug and socket. Second, the power switch on the machine itself — on Performance models it's at the back, on others it's underneath the base on the left, beneath the water tank — which must be set to I. Third, that there's water in the tank. If all three are correct and it's still dead, contact your retailer for a warranty claim.
Why is my Wilfa coffee maker not pumping water?
Limescale is the cause in almost every case. Descale the machine with a proper descaling solution, run a full tank of clean water through to flush it, then test again. A badly neglected machine may need two descaling cycles.
Why is my Wilfa filter holder overflowing?
Usually because the flow setting on the filter holder doesn't match the amount of water in the tank — set 0.5 on the holder for 0.5 litres of water. Also check that the drip stop is open, that your coffee isn't ground too fine, and that the valve is clean. To clear it now, set the flow to 1.25 and rinse the holder under running water.
Is it normal for a Wilfa coffee maker to be noisy?
Yes. Wilfa's Performance and Zense machines use a pump rather than a flow-through heater, which is what holds the water between 92 and 96°C throughout the brew. The pump also empties the system after each cycle, so the noise is loudest at the start and the end of brewing. It's normal operation.
My Wilfa button is blinking rapidly — what does that mean?
A rapid, continuous blink indicates an internal fault that isn't user-repairable and has no authorised service route. Contact the retailer you bought the machine from, with proof of purchase, and make a claim under the five-year warranty.
Every UK model's manual is on the Wilfa product manuals page, and if it turns out to be a warranty matter, the warranty information page sets out exactly what's covered.
And if the machine is working perfectly but the coffee still isn't right, that's a different problem with a much easier fix — start with how much coffee to use per litre.
